Verbs and their endings

Question

Say someone said to you, "Bailo los lunes," meaning, "I dance on Monday." You wanted to say, "I like to dance too," but you did not know the correct verb ending for bailo ( I dance ) . Now I know it is "bailar" (to dance) but if it was a verb you were not sure of, is there any way to know whether it is -ar -er or -ir so that you can change who is doing it and such? Thank yo very much!

Answer 1

You need to memorize the verbs. It is the only way.

However, among the 1000 most used verbs, 75.3% are -ar verbs; 12.8% are -er verbs, and 11.9% are -ir verbs. If you consider every verb in Spanish, the ones ending in -ar are 88.7% of all the verbs. So, if I were you, and I had to guess, I'd guess -ar.
